Enum VariableExpression

pub enum VariableExpression {
    Eq(Box<dyn Variable>, Float),
    Lt(Box<dyn Variable>, Float),
    Gt(Box<dyn Variable>, Float),
    And(Box<VariableExpression>, Box<VariableExpression>),
    Or(Box<VariableExpression>, Box<VariableExpression>),
    Not(Box<VariableExpression>),
}

Expressions which can be used to compare Variables to Floats.

Variants

Eq(Box<dyn Variable>, Float)

Expression which is true when the variable is equal to the float.

Lt(Box<dyn Variable>, Float)

Expression which is true when the variable is less than the float.

Gt(Box<dyn Variable>, Float)

Expression which is true when the variable is greater than the float.

And(Box<VariableExpression>, Box<VariableExpression>)

Expression which is true when both inner expressions are true.

Or(Box<VariableExpression>, Box<VariableExpression>)

Expression which is true when either inner expression is true.

Not(Box<VariableExpression>)

Expression which is true when the inner expression is false.
